This position paper proposes that the notion of glocalization can provide valuable insights into English as a lingua franca (ELF) in the practice of English language teaching worldwide. Glocalization shares some common grounds with ELF, which is an emerging phenomenon in which localized expressions used by non-native English users achieve a measure of legitimacy. This work will first situate Taiwan's English education in the context of globalization as an example, before moving on to a discussion of the glocalization of the English language, and the need for glocalizing education policies and practices. This paper concludes by highlighting some of the implications which glocalization has for English language teaching and teacher education in Taiwan.
